In the UDOO VISION board, audio functionalities are provided by a Cirrus Logic CS4207 High Definition Audio Codec.
In order to reduce the space dedicated to connectors, there is a TRRS Combo Audio Socket, i.e. a
single socket which offer both stereo Line Out and Mic In functionalities.
Such TRRS Combo Audio socket can be used with any 4-poles 3.5mm diameter audio jack, with
pinout compatible with the most recent Headsets, shown in the table on the left.
